Timestamp Converter Documentation

Convert between Unix timestamps and human-readable dates in seconds or milliseconds.

Choose seconds or milliseconds explicitly, then convert the numeric Unix value to an ISO UTC date or convert a date to Unix time in that unit. Use current time fills both fields from the device clock. The Advanced panel converts a list of numeric values in the selected unit or ISO dates.

• Convert a single Unix timestamp from an API response or log.
• Get the current Unix time for testing.
• Convert a batch of timestamps from a log file in one pass.

Input

Text, files, or values entered in the browser, depending on the tool.

Output

A result shown in the browser that can be reviewed or copied where supported.

• Date parsing follows the browser's JavaScript Date implementation. Use explicit ISO timestamps with Z or an offset; timezone-less strings can be interpreted locally.
• Outputs are limited to the JavaScript Date range, and converting to seconds rounds down to the previous integer second.
